Abstract

Effects of host irradiation on the development of its parasite were investigated. Females of Bracon brevicomis readily accepted irradiated larvae of tile wax moth (Galleria mellonella) and rice moth (Corcyra cephalonica) for oviposition. However, irradiated wax moth larvae adversely influenced the viability of eggs laid on them and also the survival of the parasite grubs feeding on their bodies. The female grubs were affected more than the males. Rice moth larvae, on the other hand, exerted no significant influence on the viability of parasite eggs, but adversely affected the survival of the grubs. The progeny of parents that had been reared on irradiated larvae also exhibited some developmental changes although grown on non-irradiated host larvae, and these changes were more pronounced when G. mellonella was used as the host insect.
